- AStackWise
- BStackPower
- Cstackable configuration
- Dmodular configuration
- Efixed configuration
80What are two advantages of modular switches over fixed-configuration switches? (Choose two.)
- Aavailability of multiple ports for bandwidth aggregation
- Bneed for fewer power outlets
- Clower forwarding rates
- Dincreased scalability
- Elower cost per switch
81Which type of address does a switch use to build the MAC address table?
- Asource MAC address
- Bdestination MAC address
- Csource IP address
- Ddestination IP address
82Which network device can be used to eliminate collisions on an Ethernet network?
- Aswitch
- Brouter
- Chub
- Dfirewall
83What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames? (Choose two.)
- Adestination MAC address
- Bdestination IP address
- Cingress port
- Degress port
- Epath cost
84What is one function of a Layer 2 switch?
- Adetermines which interface is used to forward a frame based on the destination MAC address
- Blearns the port assigned to a host by examining the destination MAC address
- Cduplicates the electrical signal of each frame to every port
- Dforwards data based on logical addressing
85Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?
- ASW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch.
- BSW1 drops the frame because it does not know the destination MAC address.
- CSW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch.
- DSW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
86A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?
- AReplace at least half of the switches with hubs to reduce the size of the broadcast domain.
- BSegment the LAN into smaller LANs and route between them.
- CReplace the switches with switches that have more ports per switch. This will allow more devices on a particular switch.
